Troubleshooting
If you experience difficulties with the working of your SD8421, refer to the advice given below.
1. "The handset does not ring"
Check the base unit's mains power adaptor is plugged in and power is switched on. The base unit needs mains power for normal operation of the phone, not just for charging the batteries.
Make sure you are using the telephone line cable that was supplied with your SD8421. Other telephone line cables might not work.
2. "There is no dial tone"
Check that the handset is registered to the base station.
Check that the line cord is securely connected at both ends and is undamaged.
Check the power to the base station is on and connected.
3. "The base does not ring."
Check that the base power is ON, and the base ringer is set ON.
Check that the line cord is correctly fitted and undamaged.
4."The CHARGE light on the base unit does not come on." Check the handset is properly stationed.
Check the connections between the base unit and mains power socket.
Clean the battery charging contacts with a dry cloth.
5. "When I press the CALL button, I hear a loud noise."
The strange noise is caused by interference. Disconnect the mains power lead from the back of the base unit, and then wait for 30 seconds before reconnecting it.
6. "There is 'beep' sound while I am on a call."
You may be going out of range of the base unit. Move closer, or your call may be cut off.
Check the Battery Level symbol on the display. If it is low, recharge the batteries.
7. "I cannot make or answer calls."
